11.6 External dynamic brake

POINT

Configure up a sequence which switches off the contact of the brake unit after

(or as soon as) it has turned off the servo on signal at a power failure or

failure.

For the braking time taken when the dynamic brake is operated, refer to

section 10.3.

The brake unit is rated for a short duration. Do not use it for high dut y.

When using the 400V class dynamic brake, the power supply voltage is

restricted to 1-phase 380VAC to 463VAC (50Hz/60Hz).

(1) Selection of dynamic brake

The dynamic brake is designed to bring the ser vo motor to a sudden stop when a power failure oc curs

or the protective circuit is activated, and is built in the 7kW or less servo amplifier. Since it is not built

in the 11kW or more servo amplifier, purch ase it separately if required. Assign the dynamic br ake interlock

(DB) to any of CN3-9, CN3-13, and CN3-15 pins in parameter No.PD07 to PD09.
